Get the next item to process along with the task
AI agents call get_next_item to retrieve information from Loop MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that fetches data for processing. It has no side effects, does not execute code or external operations, and does not modify or delete data. The low severity reflects minimal blast radius even if an AI agent misuses it — it can only retrieve items already in the array.
From the tool's definition The tool 'get_next_item' retrieves the next item and associated task without modifying any data. The server description indicates it 'process[es] arrays item-by-item...storing and retrieving results' — this tool handles the retrieval/query aspect of that…
Attacks that exploit this kind of access
Get the next item to process along with the task. It is categorised as a Read tool in the Loop MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Loop MCP Server MCP server in PolicyLayer and add a rule for get_next_item: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Loop MCP Server. Nothing to install.
get_next_item is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_next_item rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_next_item. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_next_item is provided by the Loop MCP Server MCP server (smogili1/loop_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
